FAAC Gate Motor Replacement Nationwide

FAAC Gate Motor Replacement: The West Hollywood Owner’s Guide

An installed FAAC gate motor replacement in West Hollywood typically runs between $1,150 and $2,400, depending on the specific FAAC series and whether your existing mounting plate, arm brackets, and limit-switch hardware can be reused. We stock FAAC-compatible motors and control boards on our trucks and can swap most failed units the same day we diagnose them. Most owners discover the failure two ways: the gate stops mid-travel and won’t respond to the remote, or the motor hums but the gate doesn’t move. Both point to a motor or capacitor problem, and both are repairable with the right part in hand.

Which FAAC Models This Applies To

This page covers the motor unit itself, the part that drives the gate’s movement on FAAC swing and slide gate operators. The most common residential FAAC units we replace in West Hollywood are the 390, 400, 412, 415, and S418 swing-gate motors, plus the 740 and 844 slide-gate motors. If your cover plate or motor body lists a 390, 400, or 412 series number, the motor replacement part numbers are interchangeable within those series in most cases, but the capacitor values differ: a 390 runs a 6.3 microfarad capacitor, while a 412 uses a 8 microfarad. That mismatch is one gotcha we see often, and it’s why we read the capacitor label before swapping parts, not after.

For FAAC specifically, we recommend OEM or direct-equivalent aftermarket motors. FAAC’s Italian-built design uses a specific shaft diameter and keyway on swing-gate units that cheap universal motors don’t match well. A generic motor may bolt on but fail within a season because the arm attaches to a shaft that isn’t machined to FAAC’s spec. If the existing arm bracket is still intact and the gearbox isn’t seized, replacing just the motor is often the better call than a full operator swap. We’ll tell you which side of that line your equipment falls on, with photos in hand.

Signs Your FAAC Gate Motor Replacement Is Failing

• Motor hums, gate doesn’t move. This usually means the capacitor has failed. The motor gets power but can’t generate enough starting torque to move the gate leaf. It’s a common failure in West Hollywood’s heat, which shortens capacitor life.
• Gate moves slowly or stops partway and reverses. The motor’s windings or the internal thermal overload is degrading. If the motor is hot to the touch after a failed cycle, the windings are the problem, not the settings.
• Intermittent operation, worse when cold or damp. This points to moisture intrusion in the motor housing or a failing bearing. Coastal-adjacent humidity in West Hollywood accelerates this on older units with cracked seals.
• Burning smell from the operator box. That’s electrical insulation breaking down or a seized gearbox forcing the motor to draw excessive current. Shut the breaker off and don’t run another cycle.
• Gate works manually but not on the motor. If the release mechanism engages fine and the gate swings freely by hand, the motor is the failure point, not the gate itself. This is actually a useful diagnostic to do before calling.

Replacement Cost & What’s Included

In West Hollywood, a FAAC swing-gate motor replacement runs $1,150 to $1,750 installed for the 390, 400, and 412 series. Slide-gate motor replacements, which are heavier and require more adjustment time, run $1,400 to $2,400. The range depends on three things: whether the capacitor is failing too, whether the existing arm bracket can be reused, and whether the limit-switch hardware is original or needs replacement.

Every price we quote is written and handed to you before any work starts. No exceptions. The written scope includes the part number, the labor, any replacement hardware like capacitors or mounting bolts, and the documented photo record of what was found and what was installed. We photograph the old motor’s wiring position, the new motor’s wiring position, and the limit-switch settings after adjustment. You get that record, and so does our job file, under Clause 1 and Clause 4 of the Haven Standard. The warranty on the motor unit comes from the manufacturer, and our 365-Day Done Right Promise covers the labor and adjustments for a full year after the install.

DIY or Call Us?

There’s a safe middle ground here. You can absolutely do the diagnostic work: check whether the gate swings freely in manual release, note whether the motor hums, see if the capacitor looks swollen or leaks fluid. You should not attempt to replace a FAAC motor yourself. These units are wired to line voltage, the capacitor holds a charge even with the breaker off, and if the arm bracket is tensioned wrong on reassembly, a swing gate becomes a serious pinch and crush hazard. That’s not hedging. That’s the reality of 120-volt operators controlling a 300-pound moving gate leaf.

When we do the swap, we discharge the capacitor, photograph the wiring before touching it, set the limit switches to the actual travel distance plus a safety margin, and test the photo-eye and safety-edge circuits before we leave. That’s the other thing: the motor swap is never just a motor swap on a FAAC unit. The limit settings have to be re-verified against the new motor’s travel, or the gate overtravels and damages the new motor within weeks. Call (424) 321-7416 and tell us the model number on the side of the operator. We’ll tell you what we stock and what it costs.
